League of Legends v1.0.0.118
Vayne, The Night Hunter
Night Hunter (Passive): Vayne ruthlessly hunts evil-doers. She gains bonus Movement Speed when moving toward nearby enemy champions.
Tumble: Vayne tumbles, maneuvering to carefully place her next shot. She rolls toward the cursor and her next attack deals bonus damage.
Silver Bolts: Vayne tips her bolts with a rare metal, toxic to evil things. The third consecutive attack or ability against the same target deals a percentage of the target's maximum Health as bonus true damage. (Max damage vs. Monsters is capped)
Condemn: Vayne draws a heavy crossbow from her back, and fires a huge bolt at her target, dealing damage and knocking them back. If they collide with terrain, they are impaled, dealing bonus damage and stunning them.
Final Hour (Ultimate): Readying herself for an epic confrontation, Vayne gains increased Attack Damage, stealth during Tumble, and quadruple the bonus Movement Speed from Night Hunter.
